PRINCIPAL DOCUMENTS

The following  documents  have been filed as part of this Annual Report on Form
40-F:

A.   ANNUAL INFORMATION FORM

For our Annual  Information  Form for the fiscal year ended  December 31, 2006,
see Exhibit 99.1 of this Annual Report on Form 40-F.

B.   AUDITED ANNUAL FINANCIAL STATEMENTS

For our  Consolidated  Financial  Statements for the fiscal year ended December
31, 2006, including the report of independent  registered chartered accountants
with respect thereto,  see Exhibit 99.2 of this Annual Report on Form 40-F. For
a reconciliation  of important  differences  between Canadian and United States
generally  accepted  accounting  principles,  see  Note 22 of the  Notes to the
Consolidated Financial Statements.

C.   MANAGEMENT'S DISCUSSION AND ANALYSIS AND RESULTS OF OPERATIONS

For  Management's  Discussion  and Analysis and Results of  Operations  for the
fiscal year ended  December 31, 2006, see Exhibit 99.3 of this Annual Report on
Form 40-F.

DISCLOSURE REGARDING CONTROLS AND PROCEDURES.

(a)  CERTIFICATIONS.  See Exhibits  99.4 and 99.5 to this Annual Report on Form
     40-F.

(b)  DISCLOSURE  CONTROLS  AND  PROCEDURES.  As of the end of the  registrant's
     fiscal year ended December 31, 2006, an evaluation of the effectiveness of
     the  registrant's  "disclosure  controls and  procedures" (as such term is
     defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of
     1934, as amended (the "Exchange Act")) was carried out by the registrant's
     management with the  participation of the principal  executive officer and
     principal financial officer. Based upon that evaluation,  the registrant's
     principal executive officer and principal financial officer have concluded
     that  as of the end of  that  fiscal  year,  the  registrant's  disclosure
     controls and procedures are effective to ensure that information  required
     to be  disclosed  by the  registrant  in reports  that it files or submits
     under the Exchange Act is (i) recorded, processed, summarized and reported
     within the time periods  specified in Securities  and Exchange  Commission
     rules and forms and (ii)  accumulated and communicated to the registrant's
     management,  including  its  principal  executive  officer  and  principal
     financial   officer,   to  allow  timely  decisions   regarding   required
     disclosure.

     It should be noted that while the registrant's principal executive officer
     and principal  financial officer believe that the registrant's  disclosure
     controls and procedures  provide a reasonable level of assurance that they
     are  effective,  they  do not  expect  that  the  registrant's  disclosure
     controls and procedures or internal control over financial  reporting will
     prevent  all  errors  and  fraud.  A control  system,  no matter  how well
     conceived  or  operated,  can  provide  only  reasonable,   not  absolute,
     assurance that the objectives of the control system are met.

(c)  MANAGEMENT'S  ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL  REPORTING.
     The  required  disclosure  is included  in the  "Management  Report"  that
     accompanies the  registrant's  Consolidated  Financial  Statements for the
     fiscal year ended  December 31, 2006,  filed as part of this Annual Report
     on Form 40-F.

(d)  ATTESTATION  REPORT OF THE REGISTERED PUBLIC ACCOUNTING FIRM. The required
     disclosure  is included in the  "Auditors'  Report" that  accompanies  the
     registrant's  Consolidated  Financial Statements for the fiscal year ended
     December 31, 2006, filed as part of this Annual Report on Form 40-F.

(e)  CHANGES IN INTERNAL  CONTROL OVER FINANCIAL  REPORTING.  During the fiscal
     year ended  December 31, 2006,  there were no changes in the  registrant's
     internal control over financial  reporting that have materially  affected,
     or are reasonably likely to materially affect,  the registrant's  internal
     control over financial reporting.
